Figure 5-11: VOLTAGE SURGE/SAG SETUP Screen
The Voltage surge and sag screen shown in Figure 5-11 can be reached from the transient screen as
follows:
1. Scroll to the VOLT SURGE/SAG entry using the up and down cursor keys.
2. Press the ENTER key to bring up the VOLT SURGE/SAG screen.
The VOLT SURGE/SAG screen has several data fields. All data fields that are blank to the right of the
equal sign must be filled or an error message will occur when trying to leave this screen. The EVENT # is
the last data field to be filled. Entering the event data field will cause the display to return to the
TRANSIENT screen where a new selection can be made.
The VOLT/SURGE/SAG screen has the following fields:
START ø This field will show the start phase angle of the voltage transient in
degrees. Only one start phase angle per transient sequence is allowed.
The start phase angle must be in the first transient event in the list. The
start phase angle is not valid for DC transients. If no start phase angle
is required, this field can be set to RANDOM by pressing the
BACKSPACE (<-) key on the decimal keypad.
GO TO VOLT This field will set the voltage level during the transient duration in
volts
DUR SCALE Duration scale default is time in seconds. Use the Shuttle knob to
select CYCLES if desired. Note that durations expressed in cycles
may cause rounding errors if the period of the selected frequency
setting is not an integer number of mss. Thus, for 50 Hz applications,
no rounding errors occur but for 60 Hz, the 16.66
¯ ms period will
cause a rounding error when converted. The Duration scale selection
affects both the DURATION and END DELAY parameters.
DURATION Duration is the time the output voltage level will dwell at the GO TO
VOLT level. The DUR SCALE defines the time scale of this
parameter in CYCLES or SECONDS
END VOLT This is the output voltage level at the end of the transient EVENT and
after a time specified by the DURATION
END DELAY This is the time delay the voltage level will stay at the END VOLT
level before it proceeds with the next transient event or completes the
transient.
FUNCTION This field can be used to select the wave shape to be used during this
step of the transient sequence. Each step can use a different wave
shape from the available library of 50 user-defined waveforms or the
three standard waveforms. The output wave shape changes upon entry
into each step and remains in effect for the duration of the step. The
default wave shape is always the SINE (sine wave).
